The version of Edge coming with Windows 10 has asm.js turned off as Microsoft is still working on a fully stable implementation. If want to enable asm.js on Microsoft Edge, you can do it in the hidden flags-settings.

1. Open the hidden developer settings menu

Type about:config or about:flags in the address bar. This opens the developer settings menu of Microsoft Edge.

2. Enable asm.js in the JavaScript section

Scroll down to JavaScript and Enable asm.js. You can also Enable experimental JavaScript features, which might also add a bit to performance. If you face any stability issues with Edge, you can easily deactivate those two options again.
